I’ve been many years developing the essentials and how to carry them . I may or may not have my L. L. Bean super capacious backpack with me, but I almost always have the fanny pack. This is what I have when out roaming NYC at night.
-Top: PacSafe StashSafe Series 100 hip pack. It has a bunch of anti-theft features. Mainly, it’s the right size, got lots of interior pockets.
-Bottom: $9 Casio F-91W watch
-2nd row up: pen / 3-1/2″ x 5″ Moleskine notebook (v. slim) / Swiss Army knife / reading glasses that fold up. Louie gave them to me, no idea where to get them, but they are great / slim magnifying glass / tiny LED light / wallet
-Other stuff: Canon Powershot S-90 (have shot almost 3000 shots on this great little camera) / Sony Cybershot DSC TX7 for shooting seamless panoramas / iPhone and stylus (way easier to keyboard with this.
